Aggregates of cellulose-containing particles, such as particles of waste
paper and optional other vegetation or waste particles are used as a
carrier for additives such as insecticides, herbicides, fertilizers and
nutrients. The particles can be also used as a carrier for insect
repellants, preferably naturally occurring insect repellants, to repel
insects from rooms, buildings, plants, and outdoor areas, and to carry
adhered seeds onto an area to be planted with seeds.
